Q

these patients tend to exhibit such motor disorders as rigidity of upper extremities, absence or poverty of movement (akinesia), lowness of body movement (bradykinesia), buccofacial apraxia, and weakness of the legs.

Q

this non fluent aphasia is characterized by severely impaired auditory comprehension

A

Mixed Transcortical Aphasia (MTA)

19
Q

caused by extensive lesions affecting all language areas (the perisylvian region)

A

Global Aphasia

20
Q

What are the different types of fluent Aphasias

A

Wernickes Aphasia
Transcortical Sensory Aphasia
Conduction Aphasia
Anomic Aphasia

21
Q

this Aphasia is caused by lesions to the wernicke area (the posterior portion of the superior temporal gyrus in the left hemisphere of the brain)

A

Wernickes aphasia

22
Q

Wernickes area is supplied by what artery

A

the posterior branch of the left middle cerebral Artery

23
Q

these patients are usually free from obvious neurologic symptoms such as paralysis

A

Wernicke Aphasia

24
Q

this fluent aphasia is caused by lesions in the tempo parietal lobe especially in the posterior portion of the middle temporal gyrus

A

Transcortical Sensory Aphasia

25
the transcortical sensory area is supplied by the
posterior branches of the left middle cerebral artery
26
whats the difference between Wernickes Aphasia and Transcortical Sensory Aphasia
repetition is intact with patients that have TSA
27
this aphasia is caused by lesions in the regions between Brocas and Wernickes; especially in the supramarginal gyrus and the arcuate fasciculus
Conduction Aphasia
28
Disproportionate impairment in repetition is a distinguishing impairment of this aphasia
Conduction Aphasia
29
Unlike with Wernickes this type of fluent aphasia has good to normal auditory comprehension
Conduction Aphasia
30
the distinguishing factor for this one is that generally language functions except naming are relatively unimpaired
Anomic Aphasia
31
this type of aphasia is caused by lesions in the basal ganglia and surrounding structures in the left hemisphere
Subcortical Aphasias
32
What are some common Aphasia assessments
Boston Diagnostics Aphasia Examination (BDAE) Western Aphasia Battery WAB The Minnesota Test for Differential Diagnosis of Aphasia
33
Name two functional tests for Aphasia
ASHA functional assessment of communication skills for adults Communicative abilities in Daily Living
34
Most current research shows treatment for Aphasia is
effective
35
If a patient has a lesion in this region than their prognosis is better
Posterior Superior Temporal Lobe (PST)
36
What are some ineffective ways to increase comprehension
Louder Speech and video presentations of stimuli
37
What is the term for loss of previously acquired reading skills due to recent brain damage
Alexia
38
term for difficulty in learning to read, this difficulty is often genetically based and is manifested in childhood.
Dyslexia
39
term for the loss or impairment of normally acquired writing skills due to lesions in the foot of the second frontal gyrus of the brain
Agraphia
40
Term for impaired understanding of the meaning of certain stimuli even though there is no peripheral sensory impairment --> patients can feel, hear, and see stimuli but can not understand their meaning.
Agnosia
41
Auditory Agnosia is characterized by
impaired understanding of the meaning of auditory stimuli normal peripheral hearing difficulty matching objects with their sounds normal visual recognition of objects
42
Auditory Verbal Agnosia is characterized by
``` PURE WORD DEAFNESS impaired understanding of spoken words normal peripheral hearing normal recognition of nonverbal sounds normal recognition of printed words normal or near normal verbal expression and reading ```
43
Visual Agnosia is characterized by
impaired visual recognition of objects which may be intermittent normal auditory or tactile recognition of objects
44
Tactile Agnosia is associated with
impaired tactile recognition of objects when visual feedback is blocked (blindfold) impaired naming of objects client can feel with their hand
